    EXH: AR019096 ACC First Supplemental Response to Request for Production No. 2 and Interrogatory No. 5

    This legal document is part of a Pollution Control Hearings Board case in which the Airport Communities Coalition (ACC) challenged the Port of Seattle and the Washington State Department of Ecology over environmental concerns related to Seattle-Tacoma International Airport. The document lists scientific references and studies relied upon by ACC's expert witnesses, covering topics such as the effects of airport deicing chemicals on water quality, dissolved oxygen levels in receiving streams, toxicity to aquatic life including salmon and trout, and fluoride impacts on fish. The referenced research was used to support ACC's claims about the environmental impact of airport operations on surrounding waterways and ecosystems.

    EXH 245: Decl. William A. Rozeboom Support ACC Reply Motion Stay PCHB 01-133 01-160

    This legal declaration by William A. Rozeboom, filed before Washington State's Pollution Control Hearings Board, challenges the Port of Seattle and the Department of Ecology over their environmental review of Sea-Tac Airport expansion. Rozeboom disputes the adequacy of water flow modeling used to assess impacts on Walker and Des Moines Creeks, argues that wastewater system effects on stream flow were improperly ignored, and contends that the proposed mitigation conditions in Ecology's 401 Certification are insufficient. He also challenges claims that the Port fully complied with King County's Surface Water Design Manual, noting the Port exempted itself from key drainage review requirements.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

Read This!

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
